IMPLEMENT ATTACHMENT.

Specification of Letters Patent.

Application filed September 3; 1912. Serial No. 718,207.

lb all whomit may concern:

Be it known that, I, W'I EY J. DUNHAM, a citizen of the United States,'risiding at Berea, in the county of Cuyahoga and State of Ohio, have invented anew and useful Improvement in- Implement Attachments, of which the following is a specification, the principleot the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other invent-ions.

My invention while relating broadly to implement attachments is more particularly associated with an auxiliary and complemental pulverizinp device.

The object of the invention is to widen the cut of the machine in question to or beyond the estent of the superstructure, in order that the soil may be cultivated by pulverization close up to fences, trees and other field fixtures.

The said invention consists of means which are hereinafter described and particularly pointed out in the claims.

The annexed drawing and the following descriptionset'forth in detail certain means embodying my invention, the disclosed means, however,- constituting but some of various mechanical forms in which the principle'of my invention may be applied.

\Vith reference now to the drawing, Figure I is a plan of an implement embodying;

my invention, with certain parts broken away. same. Fig. III is a like elevation of one modification. Fig. IV is a similar view of a. second modification.

[mplement.The structure of the imple- 4 ment represented, and in conjunction with .the beams isany approved type of pole at which is as usual reinforced laterally bymeans of the braces a and a. Alined and rotatably mounted between the supports ,A and A are a plurality of pulverizing disks B having cutting edges 7). These disks constitute the forward gang inthe double gang implement which has been selected for illustration.

Fig. II is aside elevation of the.

livotally mounted upon the forward supports A. and A, in a manner which it will not be necessary to describe since it forms no part of the conception at issue, are another pair of supports C and C. These are adapted to be restricted as to lateral dis placement during their pivotal movement by the guide arms a and a. The rear supports C and C are shown held t 'ther by a single beam 6- of like designn i sucla way that each of the disks D is in-" termediate and preferably midway of some forward pair. A rcsihentseat support is indicated an milarly mounted for rotation between the supports Patent-ed Oct. 14, 1913.

hence designated as E, while a similar fragment of the retaining chain extending toward it is supplied with the reference charactor I 1! ttaclrpwnt-The preferred form of and location tor the attachment proper is seen in Figs. I and II. It will be noted'thatone is provided at each lateral end of the imple ment andinasmuch as they are in'a. patent able sense identical both will be designated pening. The imaginary axis of-this opening should rest in the same horizontal plane as the axes of .thc forndird and rear gangs. A suitable axle. g is disposed in this opening and secured through the medium of the cap and cotter pin g so that it projects a chosen distant-routwardly beyond the superstructure of the implement as a whole. One

ormore. in this instance two, additional pulvex-rain disks .II- are likewise rotatably mounted upon the axle g and held in place by another cotter-ping".

'l'he auxili::r disks II .on the attachment are positioned so r1: their cutting edges l are as is best seen in Fig. II, corresponding ly spaced from each other asany two adjacent of the disks D. The disks H and I) are furthermore of like size and the. former, as disposed rearwardly, constitute a c0mof the rearward .of the forward gang,

' plementive operative alinement with respect to the latter or rear gang and together they occasion a continuous and uniform pulverizing operation in the direction of the moving im lement. v

therwise phrased the cutting edge of the inner of the disks H cuts or pulverizes on an operative line parallel with and equally spaced from, both the line traversed by the cutting edge of the disk H which is adjacentto -it and the line traversed by the cutting edge of the proximate outer disk D. Consonantly the inner surface of the innerof the auxiliary disks H should preferably and does lie in the same plane as the outer surface of the proximate outer of the rear disks D, and consequently the attachment as an entirety may be said to be in uniformly continuing operative alinement with respectto a given gang.

-- The modified form shown in Fig. 1H discloses the attachment fastened to the forward gang and specifically to the forward beam a} In this event the disks H should best conform in size, and be spaced laterally in similar wise relative, to the forward instead} gang. The parallel opera! tive cutting lines of the disks H would, during the application of this mod ification be equally spaced both from each other and from that'line cut by the proximate end disk whereby a continuously uniform alinementwould be established and likewise a continuousl uniform pulverizing operation across, t 1e entire width of the implement.

The modification represented in Fig. IV

similarly limits the attachment in'so far as it is not independently movable with the rear gang. -Here it is again rearward ly located though attached to the rear beam a of the forwardgang. The curvature of the bracket g is necessarily heightened in an upward di;v rection in order to avoid interference with the independent'iipward movement of the rear gang.

Having now fully described my invention, what I claim and desire to secure by Letters Patent is:

1. An implement attachment comprising the combination with an implement; of a: pulverizer gang, having a plurality of disks, pivotally mounted upon opposite ends of said implement so as to have'independent vertical movement, a bracket fixedly secured to said gang and projecting laterally beyond laterally of both said bracket and said imple ment, the said disk being disposed in coinplementive operative aline'nent with respect to-said gang.

2. An implement attachment comprising the combination with a'pulverizer gang having a plurality of primary disks; of a member movably connected to the outer side thereof so as to have independent vertical movement,-an outer side bracket secured to said member, and a secondary pulverizing disk supported upon such bracket and disposed laterally of said gang and of the plane of the corresponding outer edge of said implement, the said disk being furthermore spaced in corresponding operative 'alinement with respect to the proximate end disk of said gang.

3. An implement attachment comprising the combination with a pulverizer gang hav ing a plurality of laterally alined contiguous isks; of a bracket secured at one end of said gang and projecting outwardly with respect thereto and beyond said gang, and a lurality of similar auxiliary disks mounted for movement upon said bracket and beyond said gang, such au.\ 'iliary disks being likewise contiguous and disposed in continuing operative alinement with respect to the proximate end disk of said gang.

4. An implement attachment comprising the combination with a pulverizer gang having a plurality of laterally alined primary disks; of a downwardly projecting bracket attached to said gang and provided with an opening-an axle horizontally supported in said opening and projecting laterally of said gang. and a plurality of similar and auxiliary disks rotatable upon said axle, the inner surface of the inner of said auxiliary disks being disposed in the same plane as the outer surface of the corresponding end one of said primary disks. a
